Anyone using MediaJoin?

While skimming the Sunday edition of the local paper yesterday, I came across a tech column that mentioned a piece of freeware called MediaJoin. It seems to do what the name implies, joining two or more audio/video files into a single file. What’s impressive is the list of supported file formats: MP3, WMA, WAV, OGG, AVI, MPEG-1, MPEG-2 and WMV. MediaJoin is on my list of goodies to download and give a try, especially given the price tag.
